Actually the blades for them come in a big roll. You actually make them with the saw!!! Yes really, look at the lower left corner, there are several odd looking critters on the machine. What they are is the cutter,welder,and grinder. Like any bandsaw each has a blade length, you cut the length that will make the blade,butt the ends in the welder, ZAP em, hit the anneal button, then with the little grinder make the weld flat.
